Jane Fonda is fonda Kelly Cutrone. The screen legend had the People’s Revolution publicist over to the LA house of her boyfriend, music producer Richard Perry, to see the season finale of Bravo’s “Kell on Earth” on Monday “and toast her success,” Fonda wrote on her Web site. “What people don’t know is that she wrote some fantastic songs that Richard produced in the late ’90s, which is how he knows her and how I met her.” Cutrone was signed by Ahmet Ertegun to the Atlantic label in 1996. “She’s a fierce character,” Fonda said.
